LAMP-FILLING INDICATOR.

SPECIFICATION forming part of Letters Patent No. 445,565, dated February 3, 1891.

Application filed May 1, 1890. Serial No. 350,160. (No model.)

To aZZ whom it may concern:

Be it known that I, LEWIS N. LUsK, a citizen of the United States, residing at Kala-- mazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Lamp- Filling Indicator, of which the following is a specification.

This invention has for its object the below described and claimed construction, in which the usersof lamps (the oil-receptacle of which is made of metal or material which is not transparent) are enabled to know when the lamp is filled with oil.

In the drawings forming a part of this specification, Figure 1 is a side elevation,with parts in section, on line 3 3 in Fig. 2. Fig. 2 is a plan of lettered details from Fig. 1. Fig. 3 is a perspective of lettered details from Fig. 1. Fig. 4: is plan of lettered details showing changes. Fig. 5 is a section on line 6 6 in Fig. 4, looking from a point at the right; and Fig. 6 is an elevation of lettered details from Fig. 4.

Referring to the lettered parts of the drawings, A represents a lamp, the oil-receptacle of which is made of metal or material which is not transparent. B represents the orifice to said receptacle, in which the oil is poured from the can when filling the lamp.

In the interior of the lamp A a float O is pivoted at S. Said float may be made of metal with a hollow interior, as here shown, or it may be made of cork or any other suitable material which will float upon the top of the oil and raise as the lamp is filled. This float is provided with an upward projection t', which projection extends up through the orifice B, as shown in Fig. 1. At D is a spring-actuated plate, pivoted to the lamp at 11. At 9* is shown a spring, which bears down upon said plate, and hence when said plate is raised it is raised against a spring-resistance, as will appear in the description of the operation.

In Figs. 1, 2, and 4 is shown a rod a, which has slide-bearings in the plat-e D at 2 3. The outer end of this rod (1 is passed into a slot 0 in the side wall of the orifice B, and is brought into an engagement with the upper end of the projection z of the float C, so that when the float is raised by the oil the projection 2' will be disengaged from the end of the rod a, at which time the spring-actuated plate D and its rod a will descend.

In Fig. l at F. is shown abell mounted upon the lamp A. Attached to the spring-actuated plate D is a bell-clapper i, which clapper strikes the bell when the plate D descends, and thus a signal is given indicating that the lamp is filled with oil.

In Figs. at and 5 is shown a modification in which the bell E is placed near to the orifice B. In this modification the spring-actuated plate D is provided with the bell-clappert, at-

tached to the front end, as shown in Figs. 4 and 5, in a manner to strike the bell A on the outer surface when the plate D descends.

\Vhile either plan may be adopted, that in Figs. 4c and 5 is deemed preferable, for the reason of greater compactness and a louder signal of the bell being obtained.

The spring-actuated plate D may be provided with a handle 6 for raising it when setting the signal; or said plate may be provided with rearwardly-projecting step or handle a for bearing down upon with the fingers, and thereby throw up the opposite end of said plate.

In Figs. 1 and 3 the float is shown provided with a weight m at the side of the fulcrum s which is opposite to that of the float. This weight is designed to partially counterbalance the float, and thereby cause said float to be more easily raised by the oil; but this weight will not be necessary in all cases.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination of a lamp, a float fnl crumed in said lamp and provided with a pro jection extending out of the lamp, a springactuated latch provided with a clapper and adapted to be interlocked with the projection of the float, and a bell in position to be struck by the clapper when the latch descends, substantially as set forth.

2. In a lamp, the combination of the float having the projection, the hinged spring-actuated latch provided with a clapper and with a handle to raise the latch by, and a bell, sub stantially as set forth.

3. The combination of a lamp, the ful- In testimony of the foregoing I have here crnmed float having the weighted end beyond unto subscribed my name in presence of two 10 the fulcrum and. having the projection, a Witnesses. spring-actuated latch adapted to engage said I EWIS N LUSK 5 projection when raised, a clapper attached to said latch, and a bell in position to be struck Vitnesses: by said clapper when the latch descends, sub- BELLE O.
